【问题标题】：Failed to instantiate [org.springframework.cloud.stream.binding.BindingService]: Factory method 'bindingService' threw exception无法实例化 [org.springframework.cloud.stream.binding.BindingService]：工厂方法 'bindingService' 抛出异常
【发布时间】：2019-11-07 03:21:48
【问题描述】：

我正在尝试使用 Spring Cloud Stream 和 Apache Kafka 作为流绑定器来开发事件驱动架构。

Spring Boot 版本：2.1.9 发布 Spring Cloud 版本：2.2.1 发布

我尝试了与 Greenwich.SR3 云版本相同的配置，但同样的错误。

在将应用程序作为 Spring Boot 应用程序运行时，在控制台出现以下错误。

【问题讨论】：

标签： spring-boot apache-kafka-streams spring-cloud-stream

【解决方案1】：

您似乎没有为 Validator 类添加依赖项。在您的pom.xml 文件中添加以下内容。

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.0.Final</version>
</dependency>

编辑

要添加所有与验证相关的依赖项，请添加以下内容：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
    <version>${spring-cloud-stream.version}</version>
</dependency>

【讨论】：

否，添加依赖项并不能解决问题。现在出现以下错误 org.springframework.beans.factory.UnsatisfiedDependencyException：创建 org.springframework.cloud.stream.config.BinderFactoryConfiguration 中定义的名称为 'integrationMessageHandlerMethodFactory' 的 bean 时出错：通过方法 'messageHandlerMethodFactory' 参数 1 表达的依赖关系不满足；
您能否将您的 artifactId 从 spring-cloud-stream-binder-kafka-streams 更新为 spring-cloud-stream-binder-kafka 并重试？如果您收到错误，请提供来自堆栈跟踪的caused by。
修改artifactid后，还是报同样的错误。在堆栈跟踪中，显示以下错误原因：java.lang.NoClassDefFoundError：无法初始化类 org.hibernate.validator.internal.engine.ConfigurationImpl
在 pom.xml 中添加 hibernate-validator 依赖项后，我仍然收到相同的错误：java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.internal.engine.ConfigurationImpl只有一个问题，我正在使用 Spring Boot。 Spring boot 不应该像管理其他人一样管理所有所需的依赖项吗？对此有任何想法。
@adityasingh，是的，你在某种程度上是正确的。 Spring boot 管理几乎所有的依赖项。但只有那些包含在spring-boot-starter-web 或其他此类弹簧靴的工件中的。因此，通过在 pom 中定义spring-boot-starter-web，它将自动下载所有在spring-boot-starter-web 中定义的依赖项。其他需要我们手动提供的依赖。

【解决方案2】：

升级到 spring-cloud-starter-stream-rabbit 的最新依赖项。

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
    <version>3.0.5.RELEASE</version>
</dependency>
